Ren Kiryu

Ren has a calm demeanor and will speak up whenever her sister has difficulty expressing herself. While calm in nature like her father Zero Kiryu, Ren does not appear to have Zero's stoicism as she is shown smiling and joking around with Ai Kuran. However, while she seems to have inherited her playful side from her mother Yuki Kuran, her blunt nature definitely resembles a teenage Zero as she states whatever Ai has difficulty expressing. Ren also inherited the kindness of both her parents, never wishing harm on others. Ren's kindness is best exampled by staying at the Moon Dormitory instead of her home to keep distance from Ai when she craved her sister's blood. Unlike Ai, Ren knows what a "job" is, even explaining what one generally is; the topic came up when Kaname Kuran considered getting one, until Ren informed him that the Kuran family has wealth and resources. Ren knows about this due to attending Day Class in her childhood. Thanks to this, Ren also has experience cooking, as opposed to her sister. Even as a child, Ren showed a good deal of common sense, as she promised her mother to not reveal her true identity to her classmates or take energy from them in exchange for attending Day Class. Thanks to Ai doting on her as a child, Ren is very close to her older sister. Even as a child, Ren showed an interest in the role of protector as she would take the role of "knight" when she played dolls with Ai; she spent more time with Zero to learn how to use a gun, because she wanted to protected others with her own. When she got her fangs, Ren stayed away from Ai because she craved her blood (ironically enough) and the very thought of draining her dry scared her; she would dream of it, only worsening her self-hatred, as she had promised to protect her sister. She hates to remember this time in her life, because it was when she felt the most helpless.
